There's no time like the present to catch up on some much-needed self-care. That could include spending quiet time with a new book, starting a new workout routine — or looking for ways to brighten your smile.
Many options for whitening your teeth at home are now available, from toothpastes and mouthwashes to easy-to-use whitening strips and light-activated kits. Before using any of these over-the-counter products, however, know that some light-activated kits use hydrogen peroxide along with LED blue light technology to speed up or enhance the whitening process.
Research is mixed on whether the use of light improves teeth whitening — and whether it’s worth the risk to your smile. Some studies have found that using LED technology can increase the effectiveness of teeth whitening. But the hydrogen peroxide used to bleach your teeth can also soften your enamel and cause tooth sensitivity. If you experience sensitivity from whitening your teeth at home, stop until you can consult with your dentist.
